CHAIR-PLATE FOR COMPOUND RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 461,729, dated October20, 1891.

Application filed July '7, 1891. Serial No. 398,645. (No model.)

To all whom it may concern.-

Be it known that 1, PETER BARGION, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Chair-Plates forCompound Railway-Rails; and I do hereby declare the following to be afull, clear, and exact description of said invention, such as willenable others skilled the art to which it most nearly appertains tomake, use, and practice the same.

My invention has relation to certain new and useful improvements instreet-railway chair-plates, which will be hereinafter more fully setforth in the drawings, described, and pointed out in the specification.

My improved chair plate or brace is adapted to be used more especiallyin connection with compound street-railway rails and to pass beneath thebase-rails at the point of union, in order to provide a firm brace orfoundation for the rail-joint for the purpose of providing against jolting or sagging of the rails at their ends, due to motion of the cars,loose or uneven road-beds, thereby giving a smooth and cess may be hadto the bolt-nut without disturbing the surrounding pavement.

Referring to the drawings forming a part of this specificatiomwhereinsimilar letters of reference denote corresponding parts, Figure 1 is aperspective view showing chair brace or plate secured in position; Fig.2, a cross-section on line at m, Fig. 1 and Fig. 3, a detail view of thechair brace or plate;

The letter A indicates the sub or base rail provided with a broad baseand vertical flanges a a, which extend upward a short distance on eachside of the central line, thus formingalongitudinal openingb,withinwhichthe depending stem 1) of tread rail B is adapted to fit and be securedtherein by means of bolts 13', extending through the vertical flangesand depending stem.

The chair brace or plate is'represented by the letter O, and said bracefits beneath the sub or base rail, so as to receive the end of eachrail, thus forming a solid and even foundation at each joint of thetrack, thereby preventing sagging of the rails at their weakest point,consequently providing an even surface to the tread-rail. The sub orbase rail is united to the chair brace or plate by means of bolts 0, andby means of shoulders or projections c the same is prevented fromlateral movement, consequently holding the rail in true line, whethersecured thereto or not. The

brace-plate is provided with flanged ends 0',

which extend upward on each side of the rail and the height of thetread-rail. 'The pavement adjoining the track being laid orbuilt aroundthe flanged ends, it is obvious that side pockets d are formed thereby,and inasmuch as said brace-plates are placed beneath the point ofsecuring the rails it will be noticed that ends of bolts B projecttherein. These side pockets are filled by loose blocks or removablesection of the pavement, so that in case it becomes necessary to repairthe rails the upper or tread rail may be easily removed withoutdisturbing or destroying the adjoining pavement.

It will be thus observed that my improved chair brace or'plate not onlyserves to provide a level and solid foundation for the rails at theirweakest point, but also tends to keep the adjoining pavement in propercondition during repairs of the road. By removing the loose blocks orfilling from the pockets easy access may be had to the securing-boltsfor the rails in order to remove the tread-rail or make repairs.Intermediate the chair-plates the pavement fits closely against therails,

and thus tends to give strength and solidity- Having thus described myinvention, what I claim as new, and desire to secure protection in byLetters Patent of the United States, 1s

1. The combination, with a compound railway-rail, of achair-plate uponwhich the lower rail bears, said plate extending upward on each side ofthe rail so as to provide side pockets, into which the securing-bolts ofthe rails extend, as and for the purpose set forth.

2. The combination, with a compound railway-rail, of a chair-platepassing under and secured to the sub-rail, said plate provided withflanged ends extending upward on each side of the rail so as to formpockets, into PETER BARGION.
